8.5 CRACK TIP PLASTIC ZONE SIZE ESTIMATION As you know by now, a
region of plasticity is developed near the crack tip whenever the stresses
described by Eq. 8-18 exceed the yield strength of the material. An estimate of
the size of this ...
FIGURE 8.9 Onset of plastic deformation at the crack tip. "Effective" crack length
taken to be initial crack length plus the plastic zone radius. the apparent crack
length is increased by that amount. In effect, the plastic zone diameter is a little ...
which is only about 2% greater than A,pPijed- When the plastic zone is relatively
small in relation to the overall crack length, the plastic zone correction to the
stress intensity factor is usually ignored in practice. This occurs often under

This is one of the best textbooks on physical metallurgy. My preference is for Dieter's book, but that is because it was the textbook for my physical metallurgy course in graduate school. Hertzberg's book is more modern. Read full review
